Thanx Scott, I have taken the plastic T out already (actually there is two T's - one is connected to its pipes with special non removable clamps and the other one is just below that connected with normal clamps). It WAS quite a challenge getting them out :-)
Both looked fine to me so I am still searching for my leak. This little white T in my picture is the only thing I found broken - and the description on the PET for its replacement (it forms part of it) is called the "Vent Line Bleeding Crankcase" just for information.

Definitely replace the plastic T's. They get brittle and crack. They are very difficult to get to even when you have the manifold off changing the coolant pipes. Mine were not change at the time the coolant pipes were changed with the first owner and then cracked on me months later. Pain in the Butt. Sorry I can't help with the identification of the other little white T.
The black tees are hard plastic t-joints connecting 1" wide black rubber coolant hoses with metal compression bands. If memory serves me, these live only on the turbos, and they are way back there and very hard to find and change out. If you have a turbo, follow the right-most top coolant pipe as it drops back to the right at about a 45 degree angle to the ground. These are also known to eventually go bad, independent of the famous plastic coolant pipes, and the consensus is to definitely do them while you're in there. It's a hard, hard, hard few hours with specialized spring-loaded pliers and box-cutters and bruised knuckles and cuts in a 2-inch by 4-inch space you can't see, but they have to be replaced one way or the other. I fought with mine for 2 or 3 hours, but lo and behold, it was crusted over with leaking coolant from the joints. I posted pics on here somewhere...
The white tee in your picture in the first post is exactly what you said - attaches to a vent line that runs up the passenger side of the cylinders and crosses over to the driver's side. No coolant, and honestly I have no idea what would happen if you drove it like that. But mine also sheared off exactly like that when I moved the vent line toward the passenger's side, and I didn't notice it until I put it all back together.
Now you have to fix that vent line somehow. Very different problem than the coolant issues though. It can be repaired with similar connector tees from any auto parts store for about $3, or you can buy the whole vent line from Porsche for over $100. But the real work will be getting the old one out from the black hoses in your picture.
